If he starts every time ERod starts plus a couple here and there, he may get just 40 games as a catcher, barring a Vaz injury.
Maybe he plays some at 1B, but we have Moreland and Pearce (who has shown he can hit righties better than Swihart), and Holt can play 1B and may be in need of some PAs to stay sharp.
Maybe he plays some OF, but with everyone healthy, JD should play OF in NL parks and/or when an OF'er needs a rest. Holt can also play OF (see 1B comment).
I doubt he plays 3B or 2B, unless there is an injury. We have Nunez and Holt, and would call-up Lin if an infielder gets hurt.
I'm still not sure Swihart gets "the chance" everyone is waiting for.
